To determine the likelihood of the kittens inheriting the genetic condition, we can create a Punnett square to show the possible combinations of alleles that the offspring could inherit from their parents.
Parent 1 (female) genotype: DD
Parent 2 (male) genotype: DD
Punnett square:
D (normal allele) D (normal allele)
D (normal allele) DD DD
D (normal allele) DD DD
All of the offspring from this cross will have the genotype DD, meaning they will all inherit the normal allele from both parents. Therefore, the percentage of offspring expected to have the genetic condition is 0%.
A female cat (a queen or a molly) and a male cat (tom or tomcat) produces offspring. We want to determine the likelihood that the kittens will inherit a genetic condition. The dominant allele (D) produces the normal phenotype, and the recessive allele (d) produces the genetic condition. Both the male and female cats have the normal phenotype.
Identify the percentage of offspring that are expected to have the genetic condition based on this punnett square
